Overview
Long Island (known locally as Arop) is a volcanic island in Madang Province, Papua New Guinea, situated in the Bismarck Sea roughly 80–90 km north of the Madang coast. It is one of PNG's more remote destinations and sees very little international tourist traffic, making it genuinely off-the-beaten-track.
The island is dominated by a large flooded caldera lake — Lake Wisdom — formed after a catastrophic eruption believed to have occurred in the late 17th or early 18th century. That eruption is thought to have caused significant regional disruption and may be connected to volcanic winter records from the period. Today the lake and surrounding rainforest are the island's defining natural features.
The population is small and spread across a handful of coastal villages. Life is subsistence-oriented, centered on fishing, gardening, and community. Visitors who make the effort to reach Long Island are rewarded with quiet beaches, pristine reef diving, and an authentic encounter with Melanesian village life that is increasingly hard to find elsewhere in the Pacific.
Before You Go
Visas
Papua New Guinea has its own visa requirements that vary by nationality. Do not rely on this guide for current visa rules. Check TravelerPulse's Visas section and the official PNG Immigration & Citizenship Authority website for up-to-date requirements before you travel.
Health
Malaria is present throughout Madang Province including Long Island. Consult a travel medicine specialist well before departure — prophylaxis, insect repellent, and long-sleeved clothing are strongly advised. Ensure your routine vaccinations are current; hepatitis A and typhoid vaccinations are commonly recommended for PNG travel. There are no reliable medical facilities on the island itself; the nearest hospital-level care is in Madang town. Comprehensive travel health insurance including medical evacuation cover is essential.
What to Bring
- Cash in PGK (kina); there are no ATMs or card facilities on the island
- Personal medical kit including any prescription medicines, rehydration salts, and malaria treatment
- Snorkeling or dive gear if you have it (rental availability on the island is not guaranteed)
- Modest clothing respectful of local custom
- Water purification tablets or a filter, as treated water is not available everywhere
- Torch/headlamp, as power is limited or absent in many areas
Getting There
By Air to Madang
The main gateway is Madang Airport (MAG), which has scheduled domestic connections to Port Moresby (Jacksons International Airport) and occasionally other PNG cities via Air Niugini and other domestic carriers. Flight schedules and availability change frequently — verify current routes and book well in advance.
Madang to Long Island
From Madang, the onward journey to Long Island is typically made by small motorized boat (banana boat or fibreglass dinghy). The crossing can take several hours depending on the vessel and sea conditions, and it can be rough, particularly during the northwest monsoon season (November to April). There is no regular ferry service; arrangements are generally made locally through guesthouses, village contacts, or operators in Madang. Ask at Madang's harbor area or through your accommodation in Madang for current options.
Given the logistical complexity, it is strongly recommended to arrange the crossing before you leave Madang rather than trying to improvise on arrival. Some dive operators based in the Madang region include Long Island on itineraries — booking through one of these may simplify logistics considerably.
Getting Around
Long Island is small enough that most movement between villages and to key sites is on foot along coastal and forest tracks. There are no paved roads and no formal vehicle hire.
For lake access or inter-village travel by water, small canoes or dinghies are sometimes available through local contacts. Always agree on arrangements and any contribution expected before departing.
Trekking to Lake Wisdom involves a moderately challenging walk through dense rainforest. A local guide is strongly recommended — not only for navigation but also out of respect for customary land ownership. Ask village leaders (ward councillors or village elders) to help you arrange a guide; expect to pay a fair and agreed fee.
Where to Stay
Accommodation on Long Island is extremely limited. There is no hotel infrastructure. Visitors typically stay in basic village guesthouses or with local families, arrangements that are usually made through contacts in Madang or via advance communication with village leaders.
Expect very basic conditions: shared facilities, limited or no electricity, rainwater for washing, and simple local food. Bring a sleeping bag liner or light sheet. These arrangements rely entirely on local goodwill and community hosting — treat your hosts with courtesy and follow their customs.
Some travelers visit Long Island as a day excursion or overnight stop on a liveaboard dive vessel, which provides its own accommodation and meals. This may be the most practical option for those wanting greater comfort and logistical certainty. Verify liveaboard operators and routes with Madang-based dive companies.
Things to See & Do
Lake Wisdom
The flooded volcanic caldera is the island's most dramatic natural feature. The lake is large, deep, and ringed by forested crater walls. The hike to reach it traverses rainforest and is rewarding for those who enjoy wilderness walking. Swimming in the lake may be possible; verify locally regarding any customary restrictions or safety considerations.
Diving and Snorkeling
The reefs around Long Island are largely undisturbed and support healthy coral and diverse marine life. Diving here is genuinely remote — there are no dive shops on the island in the conventional sense. Divers typically visit as part of a liveaboard or expedition arranged from Madang. Snorkeling off beaches can be done independently but a local guide or companion is advisable.
Village Visits
Engaging respectfully with local communities — observing daily life, attending church services (Christianity is widely practiced), or watching traditional activities — is a meaningful part of any stay. Always seek permission before photographing people or entering ceremonial spaces.
Beachcombing and Birdwatching
Long Island's beaches are quiet and largely untouched. The rainforest interior hosts birdlife typical of the Bismarck Archipelago region. Bird-of-paradise species may be present; verify with local guides.
Food & Drink
There are no restaurants on Long Island. Food is whatever the community grows, catches, or trades — typically fresh fish, root vegetables such as taro and sweet potato, greens, and occasionally rice. Hosts will generally prepare meals for staying guests; a fair contribution toward food costs is appropriate and appreciated.
Drinking water is the main concern. Rainwater collection is common but the safety of any water source should not be assumed. Use purification tablets or a filter for all drinking water. Bottled water is not reliably available; bring your own supply or purification capacity from Madang.
Avoid alcohol in community settings unless your host indicates it is appropriate. Many PNG communities, particularly those with strong church influence, prefer a dry environment.
Practical Information
Money
Bring all the kina you will need from Madang. There are no banking facilities or ATMs on the island. Keep small denominations for paying guides, contributions to hosts, and any small transactions.
Connectivity
Mobile coverage is limited or absent in much of Long Island. Do not rely on phone or internet access. Inform someone of your itinerary and expected return before departing Madang.
Emergency Contacts
Verify current PNG emergency numbers and the location of the nearest aid post or health facility before you travel. The nearest significant medical care is in Madang. Your travel insurance provider's emergency line is likely to be your most reliable first contact in a serious situation.
Responsible Travel
Long Island's environment and communities are fragile. Take all waste with you when you leave. Do not remove coral, shells, or natural materials. Follow customary land and sea protocols, which your guide or host can explain. Any financial transactions should be agreed clearly in advance.
Safety
Long Island is generally peaceful and violent crime against visitors is not a pattern associated with this area. The primary risks are environmental and logistical: open-water sea crossings that can become dangerous in bad weather, malaria, tropical heat and humidity, and the absence of emergency services.
Always check sea conditions before the crossing from Madang. Do not pressure boat operators to travel in unsafe conditions. The wet season (roughly November to April) brings stronger winds and higher seas; plan accordingly.
Travel with a charged communication device and know the contact details for your country's embassy or high commission in Port Moresby. Register your travel plans with your home country's foreign affairs travel registration service if one is available.
Check your government's current travel advisory for Papua New Guinea before departure — PNG as a whole receives elevated advisories from several Western governments, though remote island communities often have very different risk profiles from urban areas. Use these advisories as one input among several rather than the sole basis for your decision.
Local Culture & Etiquette
Long Island's communities are Melanesian and maintain strong connections to customary land, kinship networks, and tradition alongside Christian practice introduced during the colonial era. Respect for elders and community leaders is important; decisions about land access, guides, and hosting will often pass through these figures.
Dress modestly, particularly in villages and near community buildings. Swimwear is appropriate only at the water's edge. Ask before photographing individuals, groups, or sacred spaces.
Customary ownership (kastom in Tok Pisin) extends to land, reefs, and forest. This is not merely a legal formality but a deeply held cultural reality. Accessing any area — particularly the lake interior — without local permission and guidance is both disrespectful and potentially contentious.
